## What is spline command in AutoCAD?

Creates a smooth curve that passes through or near a set of fit points, or that is defined by the vertices in a control frame. Find. SPLINE creates curves called nonuniform rational B-splines (NURBS), referred to as splines for simplicity. Splines are defined either with fit points, or with control vertices.

## What does the Flatten command do in AutoCAD?

FLATTEN results in 2D objects that retain their original layers, linetypes, colors and object types where possible. You can use FLATTEN to create a 2D drawing from a 3D model, or you can use it to force the thickness and elevations of selected objects to 0.

## What is a polyline?

## How do you explode a spline?

## What is the difference between spline and polyline?

Oh, well a spline is a continuous curve that passes through discreet points specified by the user. A polyline is a chain of points with line or arc segments linked end to end. … Splines are mathematically generated on regen in AutoCAD so they’ll always be smooth. This makes them suitable for machining toolpaths.
